1Q50.70 - Gyroscopes

Code Number:
1Q50.70
Demo Title:
Gyroscopes
Condition:
Fair
Principle:
Conservation of Angular Momentum about Vertical Axis
Area of Study:
Mechanics
Equipment:
Gyroscopes Assorted.
Procedure:

The black Gyroscope is the best one for use when showing that the Gyroscope tries to stay in the same plane.

The red Gyroscope can be hand started by rolling along a bench or pulling with a string.  When pulling with a string care must be used so that you do not pull the Gyroscope out of the gimbal.

The crank may be used to wind up the blue Gyroscope.  This Gyroscope is not very well balanced so it will probably need to be fixed to the lecture bench.

While a little small, the gyroscope with the motor starter can be quite good for gyroscopic studies.

The gyroscopic shaver was developed for use on the space shuttle/space station where electricity is at a premium.
